At = Ag+(m-1)*As
This formula uses 4 Variables
Variables Used
Transformed Area of Prestressed Member - (Measured in Square Meter) - The Transformed Area of Prestressed Member is the area of the member when steel is substituted by an equivalent area of concrete.
Gross Area of Cross-Section - (Measured in Square Meter) - The Gross Area of Cross-Section is defined as the total area of a section perpendicular to the direction of the load.
Modular Ratio - The modular ratio is the ratio of the elastic modulus of a particular material in a cross-section to the elastic modulus of the “base” or the reference material.
Area of Prestressing Steel - (Measured in Square Meter) - Area of Prestressing Steel is the total cross sectional area of tendons.

What is Loss of Prestress & What are the Losses in Prestressing Concrete?

A reduction in initial pre-stress resulting from the combined effect of creep, shrinkage or elastic shortening of the concrete, relaxation of the reinforcing steel, frictional losses resulting from the curvature of the draped tendons and slippage at the anchorage.
In a prestressed concrete beam, the loss is due to the following:
1. Elastic shortening
2. Shrinkage of concrete
3. Creep of concrete
4. Frictional loss
5. Relaxation of steel
6. Anchorage take-up

What are the Classification of Prestressing Losses?

The losses are broadly classified into two groups, immediate and time-dependent.
The losses due to elastic shortening of the member, friction at the tendon-concrete interface and slip of the anchorage are the immediate losses.
The time-dependent losses occur during the service life of the prestressed member. The losses due to the shrinkage and creep of the concrete and the relaxation of the steel are time-dependent losses.
